3.7. BATTERY AND BATTERY CHARGER
The battery for operating the Recloser’s components and control circuit is placed in the lower part
of the control cubicle and can be easily replaced. The battery life is usually 5 years, but it can be
shortened depending on how it is handled. The fully charged battery is enough for 30 hours
operation without an external power source.
